Electrical day

Yesterday morning, the batteries were down to less than 12V - not a good thing, especially as our use had not been excessive. Then I remembered, the charge controller and switched to float very early the day before and I manually reset it to bulk a couple times. Obviously it was not charging the batteries adequately even though it thought it was. I borrowed a clamp on amp meter from Brent and made sure the solar panels were performing as they should - they were. Then I went into the programming of the controller and found I had set the parameters very low during the extended period we were not using the boat to lessen the water use in the batteries. (It had, indeed, been minimal.) I reset the controller for aggressive charging and all seemed well. Not only did we bring the batteries back up nicely, we made water (uses ~20 amps) for a couple hours too. This morning when I got up, batteries were still @ 12.6. They did get some help from the newly repaired wind generator though as we had a windy night. Anyway, looks good now. The rest of yesterday was spent on various other minor electrical projects - making sure both cabins had working (and relatively quiet) fans, reading lights over the berths, etc. The biggest challenge was fixing the cockpit table light. We have a very nicely carved gourd that a friend from Providencia made for a lamp shade and it swings a bit in the breeze. Now it had stopped working. On close inspection, it appeared that one of the wires had sheared off right were it entered the body of the LED light. Not fixable. I had another LED light that projected both down and 360* out. That would be perfect in the shade and really highlight the designs created with hundreds f tiny holes. I tested it and it worked, but after I got everything rewired (replacing the switch as well as it was badly corroded), it only worked intermittently. It had the same wire issue in the same place. Tear it all down again. I have several LED clusters with 12 LEDs potted in epoxy in a package about 3/4" diam and 1" tall. I took 3 of these and twisted their leads all together - 1 pointing down and 1 out to each side. I used electrical tape to bind them together and then heat shrink tubing to transfer the load from the tape to the sturdy 2-18 sheathed wire I used to suspend it. Hopefully this will keep and loads off the actual LED clusters and preserve their delicate wires. It certainly looks nice with a bright spot on the table and gentle illumination all around through the shade. Time will tell how long it lasts. By 3:00 we cleaned up and took dinghy over to Rana Azul. (I did a test run around our island and then Dave's first to be sure it was running OK on the old fuel. It was.) We had a good time with friends. Found out that our friend Alan is sailing his boat from Bocas to Florida "as soon as I can get ready." We will probably leave first, but since we plan on stopping at several places, he will probably pass us somewhere along the way. Hopefully we can get in touch and maybe 'buddy boat' for a leg. Today we sail (or motor) back to Discovery Bay. We have a couple more things to do on the boat and then we will be ready. I probably won't post again until we are all set and about to leave. Stay tuned.
